Micron says memory supply will be much tighter in 2027 and 2028 and that over 75% of its fiscal 2027 output is already committed. Here is why AI is eating the world's RAM and how to plan your hardware budget.

Micron expects one. On its fiscal Q4 2026 earnings call, CEO Sanjay Mehrotra said memory and storage supply-demand conditions will be "much tighter in calendar 2027 and 2028 than they were in 2026," with demand exceeding supply. More than 75% of Micron's planned fiscal 2027 output is already committed, and he said the company has no line of sight to when supply and demand will balance.

AI accelerators are paired with HBM, stacked memory that feeds data to the chip fast enough to keep it busy. HBM uses far more wafer capacity per gigabyte than normal DRAM. Every new AI data center takes a share of the same factories that make your laptop's RAM, and new factories take years to build and ramp.
For people who run AI models at home, memory is the main constraint: a model has to fit in VRAM or unified memory. The thread focused on high-end cards and Macs, the RTX 5090, RTX 6000 and Mac Studio, staying expensive, and on whether running local AI is becoming a hobby only for people with large budgets.

Micron expects memory supply to be much tighter in 2027 and 2028 than in 2026, with demand exceeding supply, which typically means higher prices for DRAM and flash.
AI data centers need high-bandwidth memory (HBM), and memory makers are moving production capacity to it, leaving less for ordinary DRAM and NAND used in PCs, phones and servers.
If you were going to replace machines in 2027 anyway, buying earlier may cost less. Analysts project PC average selling prices up 17% in 2026.
Usually not. Hosted AI services and managed agents run on the provider's hardware, which avoids buying expensive memory-heavy machines.
